Application filed September 1, 1917. Serial Ito. 189353.

To all whom it may concern:

Be it known that 1, WILLIAM M. ANDER- soN, a citizen of the UnitedStates, residing at Minneapolis, in the county of Hennepin and 'State ofMinnesota, have invented certain new and useful Improvements inVentilated Water-Closet Bowls; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to ventilated water closet bowls and has for itsobject to provide means for producing a forced draft in the ventilatingstack to which said bowl is attached.

To the above end, the invention consists of the novel devices andcombinationsol devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, likecharacters indidid cate like parts throughout the several views.

Referring to the drawings,

Figure 1 is a view, partly in side elevation and partly in verticalsection, and illustrating a building and water closet in which theinvention is incorporated;

Fig. 2 isa fragmentary detail view, on an enlarged scale, with someparts shown in different positions by means of broken lines;

Fig. 3 is a detail view, principally in plan, with some parts sectionedon the irregular line 3-3 of Fig. 2; and

Fig. l is a view, principally in vertical section, taken on the line 1-4of Fig. 3, on an enlarged scale.

Of the parts of the building illustrated, the numerals 5 and 6 indicate,respectively, the floor of a bath or other room and a partitionseparating this room from an adjacent room. To the door 5, is secured acloset bowl 7, of the siphon action, wash down type, and'to the wall '8,is secured a low water tank 8 that is connected to the closet bowl 7 bya connection disclosed and broadly claimed in my co-pending application,Serial Number 155,645, filed March 19, 1917, and entitled Ventilatedwater closet bowls. This connection comprises a flushing elbow 9, havingan extensionlO that is axially alined with the delivery end thereof andconnected to a ventilating stack 11 by an elbow 12. The stack 11 islocated between the walls of the partition 6 and, as shown, theextension 10 is rigidly secured to the elbow 9 by solder and rivets, andsaid elbow is cut away to afiord a communicating passagewaytherebetween.

In the rim of the bowl 7, is the customary flushing passageway 13 andannular passageway 14, the former of which afiords direct communicationbetween the elbow 9 and bowl 7, and the latter of which hascommunication with said bowl through a multiplicity of circumferentiallyspaced holes 15. Anchored to the bowl 7, is a pair of hinge posts 16 inwhich is journaled a horizontal rock shaft 1?, having rigidly securedthereto, at their intermediate portions, a pair of horizontal levers 18.These levers 18 are located inside of the hinge posts 16 and engage thesame to hold the rock shaft against endwise movement.

The short ends of the levers 18 project forward and have the hingemembers 19 of a seat 20 connected thereto by hinge pins 21, and thehinge members 22 of a seat cover 23 are connected to the long arms ofsaid lever by hinge pins 24. The weight of the cover 23, whether open orclosed, acting 011 the long arms of the levers 18, will normally holdthe rear end of the seat 20 slightly raised, while the front end thereofis supported on the rim of the bowl 7.

Interposed in the flushing elbow 9, above the extension 10, is ahorizontal cylindrical valve casing 25, which projects radiallytherethrough from the front to the rear. Integrally formed with thisvalve casing 25, are upper and lower annular flanges 26, into which theadjacent ends of the sections of the elbow 9 are telescoped and rigidlysecured by solder to form watertight joints therebetween. Wamr issupplied to the tank 8 through a pipe 27 leading from a suitable sourceunder pressure, and a branch water pipe 28 connects the said pipe 27with the rear end of the valve casing 25. Within the valve casing 25, isa partition 29, having an axial port 30, which adords communicationbetween the receiving end of the chamher in said valve casing and thedelivery end thereof. This port 30 is normally closed by a ball valve 31arranged to close with the water pressure.

Leading from the delivery end of the valve casing 2 is a ube 32', havingon its Mill outer end a spraying nozzle 33. The tube 32 extends from thevalve casing 25, through the flushing elbow 9 toward the bowl 7, andjust before'it enters said bowl, the same is bent upon itself, so thatthe nozzle 33 projects rearwardly in axial alinement with the extension10.

When the seat is depressed, the ball valve 31 is forced from its seat toopen the port 30, by a long stem 34 which works through a stuiling boxon the front end of the valve casing 25. Endwise movement is imparted tothe stem 34 by an eccentric 36, secured to the shaft 17, and a link 37,connected at one end to said eccentric by an eccentric strap 38 andhaving its other end pivotally connected to the outer end of the stem34. The eccentric is so positioned on its shaft 17, that it normallyholds the stem 34 slightly out of contact with the ball valve 31, sothat the same may be held seated by the water pressure. At the time theseat 20 is depressed, the stem 34: is moved rearward by the eccentric36, engages the ball valve 31 and forces the same from its seat againstthe water pressure.

With the ball valve 31 open, water from the branch pipe 28 will beadmitted through the port 30 to the tube 32 and sprayed by the nozzle 33into the elbow 9 and extension 10, as indicated in Fig. 2. This waterspray will create a suction 1n the bowl 7 and produce a forced draft inthe'stack 11 through the openings 15, passageway 14, elbow 9, andextension-1Q. After the water spray has spent its force, the samewilldrain into-the bowl through the extension 10, elbow 9 and flushingpassageway 1.3. When the pressure is removed. from the seat 20, thewater spray is automatically cut off by the weight of the cover 23,acting on the levers 18 to raise the rear end of the seat 20 and turnthe shaft 17 to operate the eccentric 36., and. thereby move the stem34: out of contact witl'i its ball valve 31 to permit the same to beclosed by the water pressure.

From the above description, it is evident incense that the action of theinvention is entirely automatic and simple, with few parts to get out oforder. It is also evident that the device may be manufactured at acomparatively small cost and easily installed and, in actual usage, thesame has proven highly efficient for the purpose had in view.

lVhat I claim is 1. The combination with'a closet bowl, a water supply,a ventilating stack and a single connection between the closet bowl,water supply and ventilating stack, of a spraying nozzle connected tothe water supply, located in said connection and arranged to direct aspray of water toward the ventilatin stack.

2. The combination with a closet owl, a water supply, a ventilatingstack and asingle connection between the closet bowl, water supply andventilating stack, of a water pipe leading from the water supply andhaving a spraying nozzle located in said connection and arranged todirect a spray of water toward the ventilatin stack, a valve interposedin the Water pipe and incorporated in said connection, and means foropening and closing the valve.

3. The combination with a closet bowl, a water tank, a water supply pipeleadingto the water tank, a ventilating stack, and a flushingbendconnecting the water tank and closet bowl, said bend having an extensionconnecting the delivery end thereof with the ventilating stack, of avalve casing interposed in the flushing bend at its receiving end andconnected to the water supply pipe,

a normally closed valve in said casing, a water tube leading from thevalve casing andhaving a spraying nozzle located in the delivery end ofthe flushing bend, and means for opening said valve.

In testimony whereof I aiiix my signature in presence of two witnesses.
